This 2-channel 5V relay module is designed to control high-current AC or DC loads safely through low-voltage microcontroller signals. With a contact rating of 10A, it can handle appliances, motors, lights, and other devices directly.
The module is equipped with optocouplers to provide electrical isolation between the control logic and the relay outputs, ensuring stable and reliable operation. It can be directly controlled by 3.3V–5V logic signals from popular microcontrollers such as Arduino, AVR, PIC, DSP, ARM, MSP430, and 8051.
Each relay supports both Normally Open (NO) and Normally Closed (NC) connections, making it versatile for various automation and control applications.
